Contusion is the medical term for a bruise. When you have a low back bruise, it's often caused by a direct blow or an impact, such as falling against a counter or table. Bruises are common sports injuries.
Most people think of a bruise as a black-and-blue spot. This happens when small blood vessels get torn and leak blood under the skin. But bones, muscles, and organs can also get bruised. If these deep tissues are damaged, you may not always see a bruise.
The doctor will examine your bruise. You may also have tests to make sure you do not have a more serious injury, such as a broken bone or nerve damage. Tests may include X-rays or other imaging tests like a CT scan or MRI.
Low back bruises may cause pain and swelling. But if there is no serious damage, they will often get better with home treatment in several days to a few weeks.
The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
